What condition of windshield wipers is checked for in a Class D inspection?

Windshield wipers are a critical component of vehicle safety, as they ensure that the driver's line of sight is clear during inclement weather. In a Class D inspection, the condition of windshield wipers is specifically evaluated to ensure they are functional and effective.

Having wipers that are in working order means they should properly clear the windshield of rain, snow, or debris, which is essential for safe driving. If the wipers are overly worn, they may not effectively wipe the windshield, potentially leading to reduced visibility and an increased risk of accidents. Therefore, the inspection process focuses on confirming that the wipers not only operate correctly but also have sufficient rubber on the blades to maintain effective contact with the windshield.

The other options do not align with the primary focus of the inspection. While color-coding might apply to other parts, it is irrelevant to wiper function. Replacement schedules, like annual replacement, could vary based on use and wear rather than a strict requirement, and slightly damaged wipers could compromise visibility – thus, they would not meet safety standards for inspection.
